Two former Parramatta Eels players are accused of harbouring semi-automatic weapons and possessing more than half-a-million dollars in cash after dramatic arrests in Sydney's Centennial Park yesterday.

"It is never about being sad. It is about motivation and linking his very real story to the need to educate our children on being safe," Mr Morcombe told the Courier Mail. Another notable guest in the record-breaking crowd of more than 1000 people was the Morcombe’s latest family addition, baby Winston.

Winston Morcombe is the son of Daniel’s twin brother, Brad, and Brad’s wife Anna.

His middle name, Daniel, is a tribute to the uncle he will never get the chance to meet.

"There’s always so much hope and promise around the birth of a baby. Winston makes me smile," Denise Morcombe told the Australian Women’s Weekly.

All wearing red to commemorate the coloured t-shirt Daniel was wearing on the day he was abducted, the group walked four kilometres from the Suncoast Christian College, to the Morcombe family home in Palmwoods.

Workshops on anti-abduction and personal safety for children have been held at a number of primary schools across the country this morning.
